SPECIFICATION forming part of Letters Patent No, 269,514, dated December 26, 1882.

(No model.)

rence, in the county of Essex and State ofMas sachusetts, have invented certain new and useful Improvements in Wool-Oiling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a partof this specification.

This invention relates to certain improvements in wool-oiling machines; and ithasfor its objects to provide tor automatically supplying the oil from a tank or reservoir to the oilingchamber, and for filling the tank without admission of air to the same, as more fully hereinaiter specified. These objects I attain by the means illustrated in the accompanying drawings, in which- Figure 1 represents a longitudinal vertical section of my improved apparatus on new of Fig. 4. Fig. 2 is a vertical cross-section of the ing down upon the oiling'ehamber and oiling devices.

The letter A indicates the'oiling-chamber,.

which consists preferably of a semi-cylindrical vessel, having located within it a longitudinally-arranged cylinder, B, mounted on a shaft, U,-journaled in suitable bearings and provided with a pulley, c, at one end, by tneans of which it may be rotated by a belt or band connecting with a suitable driving-wheel. The said vessel is provided at one side with an inclined corrugated chute, D, and with pivoted corrugated fingers E, to direct or control the discharge of the oil from the cylinder B.

The letter F indicates the tank or reservoir which contains the oil to be supplied to the oiling-chamber A. This tank F is mounted upon standards G, secured to the oiling-chamber A. The tank F is preferably cylindrical, but may be of any other convenient shape.

v Through one end of tank F extends a fillingtube, H, provided with a funnel and strainer, I,at its upper end. The lower end of tube H terminates in the upper part of a chamber, K, from the lower part of which extends upward a pipe, L, terminating at l in the upper part of the tank F in such manner that as the oil is fed into the filling-tube H it is discharged into the tank F through the pipe L without admitting any air.

Mis a tube extending from the lower part of the tank F at one end to the oiling-chamber A below. Into tube M extends adouble pipe, N, through a suitable screw-threaded aperture in the top of the tank. One branch of the pipe N opens through a screw-cap, P. secured in the aperture. The other branch opens into the tank F,at its upper end, a, near the aperture. The lower ends of the two bran hes terminate within the tube M, near its lower end, to permit the escape of any air or other fluid which may be generated in the tank F.

R is a tube extending from a point above the level of the oil in tank F to the oilingchamber A below, by means of which the air necessary to permit the oil to flow automatically from the said tank F to the chamber A is admitted when the oil falls below the level ot' the lower end of said tube R at 1*, Figs. 1 and 4.

The wool is caused to move by any appropriate means below the chute D, and the apparatus is caused to operate in a corresponding motion by means of the pulley c on shaft G, and the cylinder B rotates, bringing the oil upon its surface from the -oiling-tank"A, and the fingers E, resting by their own weight on cylinder B, take off the oil from the cylinder, and by the corrugations in the fingers and on the surface of the chute D it is conveyed in drops regularly onto the wool passing below. The air-pipe N hasone branch passing through the cap P at the top of the tank F, the other end opening into the tank F, near the top, so that the oil is allowed to run into the oilingtank A from the filling-tube and funnel H until it comes in contact with the aitypipes N inside and at the bottom of the tube M. The arrangement of the several tubes is as follows: In fillingthe tank F the valve m is closed. The oil passes down the funnel and supply-pipe H into the chamber K, where the condensed air IOO above the oil forces the oil up the pipe L free from air, and it overflows at the upper end, I, and falls into-the tank F until the surface of the liquid rises up to the level of the pipe. R at T, when it will run down the pipe R and into the oiling-chamber A. The twopipes N unite at the bottom in tube M, and have been described above.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination,with the oiling-chamber A and its cylinder B, of the inclined corrugated chute D and the pivoted corrugated fingers E, for controlling the flow of the oil, substantially as specified.

2. The combinatiomwith the tank F, of the filling-tube H, provided with a funnel and strainer, and the chamber K at the lower end, and an independent tube, L, leading, into the upper part of the tank Ffrom said chamber K,

| substantially as and for the purpose described.

3. The combination, with the tank F and oiling-chamber A, of the connecting-tube M and inclosed double air-pipe N, communicating at one end with the interior of tank F and external air above, and the other end communicatingz, with the interior of the oil-chamber A, sub stantially as and for the purpose described.

4. The combination, with the tank F and oiling-chamber A, the connecting-tube M and inclosed double air-pipe N, of the tube R, leading from .the bottom of the tank F to the oiling-chamber A, substantially as and for the purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.

tICHARD DUGGAN.
